“…For example, in 1987, Halliyal et al [1] reported the successful fabrication of pure perovskite PZN ceramics by using BaTiO 3 (or BT) as stabilizer. It was later confirmed by our group [3] that a combination of BT stabilizer and novel Zn 3 Nb 2 O 8 B-site precursor are sufficient to suppress the pyrochlore formation in the fabrication of perovskite PZN-based ceramics. However so far, no work has been done on the systematic comparison between various mixed-oxide synthetic routes for the production of PZN-based ceramics.…”

“…In order to evaluate the dielectric properties, the ceramics derived from all three routes were polished to form flat, parallel faces and then coated with silver electrodes. The dielectric properties were measured at 1 kHz using a LCR meter (TH2819A) and temperature of 50 to 170 • C. BaTiO 3 into PZN lattices to form PZN-BT solid solution [3]. For PZN-C route, the second phase (∼21 wt%) correlated with pyrochlore-type Pb 1.83 (Zn 0.29 Nb 1.71 )O 6.39 which could be matched with the JCPDS file no.…”

“…The microstructural development was characterized using a scanning electron microscopy (JEOL JSM-840A). Mean grain size of the sintered ceramics was subsequently estimated by employing the linear intercept method [3]. In order to evaluate the dielectric properties, the ceramics derived from all three routes were polished to form flat, parallel faces and then coated with silver electrodes.…”

“…To overcome such problems, various processing techniques including crystal growth, sol-gel, perovskite stabilizers and B-site precursor have been introduced with various results obtained [1][2][3]. For example, in 1987, Halliyal et al [1] reported the successful fabrication of pure perovskite PZN ceramics by using BaTiO 3 (or BT) as stabilizer.…”

This chapter presents the investigation of fabrication and the physical properties of the Pb(Zr 1−x Ti x)O 3-Pb(Zn 1/3 Nb 2/3)O 3-Pb(Mn 1/3 Nb 2/3)O 3 multicomponent ceramics. The multicomponent yPb(Zr 1−x Ti x)O 3-(0.925 − y)Pb(Zn 1/3 Nb 2/3)O 3-0.075Pb(Mn 1/3 Nb 2/3)O 3 (PZT-PZN-PMnN) ceramics were synthesized by conventional solid-state reaction method (MO) combined with the B-site oxide mixing technique (BO). Research results show that the electrical properties of PZT-PZN-PMnN ceramics are optimal at a PZT content of 0.8 mol and Zr/Ti ratio of 48/52. At these contents, the ceramics have the following optimal properties: electromechanical coupling factor, k p = 0.62 and k t = 0.51; piezoelectric constant (d 31) of 130 pC/N; mechanical quality factor (Q m) of 1112; dielectric loss (tan δ) of 0.005; high remanent polarization (P r) of 30.4 μC.cm −2 ; and low coercive field (E C) of 6.2 kV. cm −1. Investigation of the domain structure of the two ferroelectric phases (tetragonal and rhombohedral) in the ZnO-doped PZT-PZN-PMnN with compositions at near the morphotropic phase boundary is described as follows: the 90 and 180° domains exist in the tetragonal phase, while the 71, 109, and 90° domains are located in the rhombohedral phase, and the widths of these domains were about 100 nm. Besides, the ceramics exhibited excellent temperature stability, which makes them a promising material for high-intensity ultrasound applications.
